c.) riding your bike
Explanation:
Playing chess doesn't require any physical challenges, just mental
While watching basketball, you don't physiclly move
Riding a bike requires physical movement and acceliration
Therefore C is the correct answer
Answer:
Limiting: Lab covers. Books produced: 75. Excess amounts: In explanation
Explanation:
Amount that can be produced with just lab covers: 75 books (150/2)
Amount that can be produced with just lined paper: 150 books (7500/50)
Amount that can be produced with graph paper: 120 (3000/25)
Amount that can be produced with staples: Approximately 83 (250/3)
As we can see, the lab covers are limiting as they can only produce 75 books. So, we can only make 75 books.
You will have 3,750 lined paper left over (or 75 books)
(150-75=75 , 75*50=3,750)
You will have 1,125 graph paper left over (or 45 books)
(120-75=45 , 75*25=1,875 , 3000-1875=1125)
And then you will have approximately 25 staples left over (or 8 books)
(83-75=8 , 8*3=225, 250-225=25)
(Hopefully this is correct, I apologize if I messed up)
Using Charles's law; which states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.
That is; V α T
Hence; V1/T1 = V2/T2 = constant
V2 = V1 × (T2/T1)
= 250 × (350/300) = 291.67 mL
Therefore; the new volume will be 291.67 mL
Answer:
8.55 × 10²² Molecules
Solution:
Step 1: Calculate the Mass of Water as;
Density = Mass ÷ Volume
Solving for Mass,
Mass = Density × Volume
Putting values,
Mass = 1 g.mL⁻¹ × 2.56 mL
Mass = 2.56 g
Step 2: Calculate Moles of Water as,
Moles = Mass ÷ M.Mass
Putting values,
Moles = 2.56 g ÷ 18 g.mol⁻¹
Moles = 0.142 mol
Step 3: Calculate Number of Molecules of Water as,
# of Molecules = Moles × 6.022 × 10²³
Putting value of mole,
# of Molecules = 0.142 × 6.022 × 10²³
# of Molecules = 8.55 × 10²² Molecules
